Abstract

The development of the valve train scuffing wear test by the CEC PL-35 group is described. This test is run on the PSA TU-3 engine, comprises a cold/low speed and a hot/high speed phase and is of 100 h duration. Oil performance is evaluated in terms of camshaft wear and follower contact pad scuffing merit rating. Studies undertaken by the group to identify those factors essential to the control of test development are described. The evolution of the test, with the introduction of a single point fuel-injected engine, is detailed and the consequences of this on severity and repeatability and reproducibility are discussed.
气门机构磨损PSA TU - 3测试的开发
介绍了CEC PL-35组气门机构磨损磨损试验的发展情况。该测试在PSA TU-3发动机上进行,包括冷/低速和热/高速阶段,持续时间为100小时。根据凸轮轴磨损和从动件接触垫磨损评价油品性能。小组为确定对测试开发控制至关重要的那些因素所进行的研究被描述。随着单点燃油喷射发动机的引入,详细介绍了测试的演变,并讨论了这对严重性、可重复性和再现性的影响。
